Introduction:
-
- Lorentzzi® LJ12A3-4-Z/BX is a popular M12 threaded 3-wire inductive proximity sensor that we have been using to measure metal objects; in our product line, we also refer to it as the LM12-3004NA.
- “LJ” means it is inductive type, “12” indicates the diameter is M12, “A” indicates the shape is cylindrical, “3” indicates three-wire system, “4” indicates the detection distance is 4.0 mm, “Z” indicates the operating voltage is DC 6-36 V, and “BX” indicates the output is NPN normally open.
- The following table is a description of more models:
-
- Our LJ12A3-4-Z/BX inductive proximity sensor housing is made of high-quality nickel-plated brass for corrosion resistance and filled with epoxy resin to achieve IP67 protection level.
- The default cable length of this proximity sensor switch is 2 meters, which is longer than other competitors.
- Typical applications include positioning moving objects, motion control and counting objects (if your application is counting, you can use it with our JDM11-6H to indicate the number of counts) and so on.
